Eventually, cankers spread throughout the tree surface, killing the tree.
We found that the stratospheric smoke originating from fires ignited by nuclear explosions in cities and industrial areas would be so dense that it would block out the Sun, making it cold, dark, and dry at Earth's surface, killing plants and preventing agriculture for at least a year.
Before the introduction of the vaccine in the early 1960s, measles - a highly contagious virus spread by air or infected surfaces - killed 2.6 million people every year.
While cleaning removes germs from a surface, disinfecting kills them by using antimicrobial pesticides, such as quaternary ammonium compounds or "quats". Some exposure to living bacteria is healthy for us.
Airway surface liquid kills bacteria using salt-sensitive peptides such as lysozyme and defensins [7], [25] that are efficient only against small inoculum sizes [25], [27].
Clostridium septicum α-toxin selectively binds GPI-anchored proteins at the cell surface and kills host cells [ 15].
The Houston snagged the towline of a tugboat on June 14 , 1989 dragging it beneath the surface and killing one sailor 10 miles southeast of Long Beach, Calif.
Roasts and steaks are less of a worry, since any dangerous organisms will be on the surface and killed by the time the internal temperature reaches 145 degrees.
"We have also been very clear that there are areas where BP and the private sector are the ones who must continue to lead the efforts with government oversight, such as the deployment of private sector technology 5,000 feet below the ocean's surface to kill the well".
Various inactivation mechanisms and molecular targets were suggested such as a reduction in RH inactivates bacteria by increasing their water loss; dehydration causes mechanical damage to the cell surface, ultimately killing the bacteria as well as a reduction in RH increases the oxygen diffusion into the bacteria and so increases the oxidative stress that could damage DNA and protein.
